Metal Magic: Deburring 

Finely acted script and editing. With a name like Paul Dye in machining, you can't lose!

I really like your videos - thanks for taking the time to create them. I’ve learned a lot from them. As a side note: I notice you have left the chuck key in the lathe (sitting in the background). I’d probably have it resting conveniently nearby, just in case someone forgets it’s there and launches it when the motor is turned on.

Great Tutorial...Thank you.

Thanks for the video! It taught me a lot! I’m a new welder and I am learning all the different technologies and terminologies! Awesome video!

I appreciate this video…my wife and I are building a set of elevators for a B-17G…all our holes are on back order so we have to drill and debut our own. It is labor intensive to say the least but good clean square holes are critical…we will order the v-block demurring tool! Thanks!

what would you recommend for deburring large holes. I need to deburr a hole i cannot reach into, 30mm diameter.

Paul, THANKS for this video. Could you answer what you do for the actual "edge" vs the "corners of the edge". I've always read that in addition to removing the burrs from the "corner" of the edge like you do, you also need to completely smooth the "middle" of the edge. Smooth meaning you can't feel anything and there is no visible cut/machine marks. Doing the steps you have can be done so quickly and easily. I find that I spend the most time making the "middle" part of the edge smooth. When I say corner above, I don't mean the corners you rounded at the end, I mean the corner where the flat portion of the part transitions to the thin portion of the edge.

Is it important to smooth the flat edge with a file, scotch brite or sand paper? By this I mean the thickness edge where it has been cut or sheared. Thanks

Hello, Mr. Dye. I live halfway around the world and I saw your video on RU-vid since i have been researching on deburring and how to do it although I am not sure if it is the solution to the problem I have on hand. I play airsoft and need to make a mod on a cylinder. I already drilled a hole, have the inside sanded with a sandpaper just to make sure there are no burrs on the inside of the cylinder. Apparently, the hole that i drilled on the cylinder seem to scratch the o ring for my piston. (electric airsoft blasters have pistons with rubber o rings to compress and push air out of a cylinder set. What do you think could be the problem? I can buy aftermarket parts that are within the specification I need, but they are not available in my country right now. Hope you can help. Thank you for reading my comment and have a good day! :)

Can you provide the name of the hand tool that you used on the edge of a piece of sheet metal to smooth out the sharpe edge. It almost sounded like you identified the tool as a: v-block.

What is the tool you use for the straight line please?
